Unscrewed Crown

[bradiowausa]

I've seen multiple sides of this in different treads. If the crown is not screwed in, how water resistant is the watch if at all?

not very well

It is still water resistant when open just not as much as when screwed down.

From my expensive experience : don't try !

The watch has the same rated protection depth wise when screwed in vs. not screwed in.

However it's just not as redundant in regards to that protection. By that I mean with one seal it is rated at 300 meters for a Sub. With the second seal it is still rated at 300 meters, however with a second seal if one is bad you still have one seal which might work.

So although it is best and adviseable to screw that crown down, it does not mean it won't work if it is not. So screw the crown down and have that watch pressure checked on a regular basis.

I have tested this. They are just as water resistant with the crown screed down as NLT screwed down. If the crown is unscrewed though, it would be susceptible to being moved when in the water which could to leakage.

I agreed!

When the crown can not screw-in, it is much too vulnerable than not screw in but you can, first you are not sure the thread is the problem or the case tube complete broke off, the worn thread inside the crown could cause the rubber gaskets break easily, the stem could easily snab off when it caught any object, it is serious situation, you could end up $3000 damaged to the movement. Should take care of it right away!
